IMPORTANT!
CAUTION: Improper installation, adjustment, alteration, service or maintenance can void the warranty.The weight of the condensing unit requires caution and proper handling procedures when liftingor moving to avoid personal injury. Use care to avoid contact with sharp or pointed edges.
Safety Precautions• Always wear safety eye wear and work gloves when installing equipment.• Never assume electrical power is disconnected. Check with meter and equipment.• Keep hands out of fan areas when power is connected to equipment.• R-410A causes frostbite burns.• R-410A is toxic when burned.
NOTE TO INSTALLING DEALER: The Owners Instructions and Warranty are to be given to the owneror prominently displayed near the indoor Furnace/Air Handler Unit.
When wiring:Electrical shock can cause severe personal injury or death. Only a qualified,experienced electrician should attempt to wire this system.• Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked.• Highly dangerous electrical voltages are used in this system. Carefully refer to the wiring diagram and theseinstructions when wiring. Improper connections and inadequate grounding can cause accidental injury or death.
• Ground the unit following local electrical codes.• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
When transporting:Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, andbend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins onthe air conditioner can cut your finger.
When installing...... in a wall: Make sure the wall is strong enough to hold the unit's weight.
It may be necessary to construct a strong wood or metal frame to provide added support.... in a room: Properly insulate any tubing run inside a room to prevent "sweating" that can cause
dripping and water damage to wall and floors.... in moist or uneven locatinons: Use a raised concrete pad or concrete blocks provide a solid,
level foundation for the outdoor unit. This prevents water damage and abnormal vibration.... in an area with high winds: Securely anchor the outdoor unit down with bolts and a metal
frame. Provide a suitable air baffle.... in a snowy area(for Heat Pump Model): Install the outdoor unit on a raised platform that is
higher than drifting snow. Provide snow vents.When connecting refrigerant tubing
• Keep all tubing runs as short as possible.• Use the flare method for connecting tubing.• Check carefully for leaks before starting the test run.
When servicing• Turn the power OFF at the main power box(mains) before opening the unit to check or repair
electrical parts and wiring.• Keep your fingers and clothing away from any moving parts.• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have
been left inside the unit being serviced.
Special warnings
WARNING
• Installation or repairs made by unqualified persons can result in hazards to you and others.Installation MUST conform with local building codes or, in the absence of local codes, with the National ElectricalCode NFPA 70/ANSI C1-1993 or current edition and Canadian Electrical Code Part1 CSA C.22.1.
• The information contained in the manual is intended for use by a qualified service technician familiar with safetyprocedures and equipped with the proper tools and test instruments.
• Failure to carefully read and follow all instructions in this manual can result in equipment malfunction, propertydamage, personal injury and/or death.
Please read this instruction sheet completely before installing the product.This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently.

Preparation of Piping
1. Cut the pipes and the cable.■ Use the accessory piping kit or the pipes purchased
locally.■ Measure the distance between the indoor and the out-
door unit.■ Cut the pipes a little longer than measured distance.■ Cut the cable 1.5m longer than the pipe length.
2. Burrs removal■ Completely remove all burrs from the cut cross section
of pipe/tube.■ Put the end of the copper tube/pipe to downward direc-
tion as you remove burrs in order to avoid to let burrsdrop in the tubing.
3. Flaring work■ Carry out flaring work using flaring tool as shown below.
Firmly hold copper tube in a bar(or die) as indicateddimension in the table above.
4. Check■ Compare the flared work with figure below.■ If flare is noted to be defective, cut off the flared section
and do flaring work again.
Main cause of gas leakage is defect in flaring work. Carry out correct flaring work in the following procedure.

1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over120°C).
2. Precautions in high humidity circumstance:This air conditioner has been tested according to the"ISO Conditions with Mist" and confirmed that there isnot any default. However, if it is operated for a longtime in high humid atmosphere (dew point tempera-ture: more than 23°C), water drops are liable to fall. Inthis case, add heat insulation material according to thefollowing procedure:• Heat insulation material to be prepared... EPDM
(Ethylene Propylene Diene Methylene)-over 120°Cthe heat-resistance temperature.
• Add the insulation over 10mm thickness at high humidity environment.

Checking the Drainage
1. Set the air direction louvers up-and-down to theposition(horizontally) by hand.
To check the drainage.1. Pour a glass of water on the evaporator using a ket-
tle.
2. Ensure the water flows through the drain hose of theindoor unit without any leakage and goes out thedrain exit.

Installation
CAUTION:After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power specialized for the air conditioner. As for the method ofwiring, be guided by the circuit diagram posted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screws which fasten the wiring in the casing of electrical fittings are liable to come loosefrom vibrations to which the unit is subjected during the course of transportation. Check themand make sure that they are all tightly fastened. (If they are loose, it could give rise to burn-outof the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltagemarked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.(Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point, fuse breaking, disturbance by the nor-mal function of an overload protection device.
• Proper starting power is not given to the compressor.
HAND OVERTeach the customer the operation and maintenance procedures, using the operation manual. (air filter cleaning, temperature control, etc.)
WARNING : Loose wiring may cause the terminal to overheat or result in unitmalfunction. A fire hazzard may also exist.Therefore, be sure all wiring is tightly connected.
